Cushings In Horses
This is also called Hyperadrenocorticism and it is caused by a disorder of the Endocrine System, in particular an adenoma (tumor) of the anterior Pituitary gland which causes the horses hormone levels to become imbalanced.
The Endocrine System
This controls the secretion of hormones which can be put directly into the blood or through the lymph system to all around the horses body. It controls growth, tissue function and development as well as helping to regulate the horses metabolism. The glands within the Endocrine system are the Pituitary also known as the master gland, Thyroid and Adrenal glands.
The Pituitary Gland
It is the anterior pituitary gland that causes Cushings Disease as it controls hormone secretion which in a horses with Cushings disease is overactive. This over activity is because the hypothalamus secretes less dopamine than it is supposed to causing the pituitary gland to increase in size.
The major hormones secreted are Folicle Stimulating Hormone (FSH), Luteinising Hormone (LH), Adrenocorticotropic Hormone (ACTH), Endorphins, Growth Hormone (GH), Prolactin and Thyroid Stimulating Hormone (TSH).
